expand (83.98-62.98i)(0,4-6i)

expand

(83.98 - 62.98 i) (0, 4 - 6 i)

0 \cdot 83.98, 4 - 6 \cdot 83.98 i - 0 \cdot 62.98 i, 4 + 6 \cdot 62.98 ii

Solution steps

(83.98 - 62.98 i) (0, 4 - 6 i)

= (83.98 - 62.98 i) (0 \cdot 4, - 6 i)

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = 83.98, b = - 62.98 i, c = 0, 4, d = - 6 i

= 83.98 \cdot 0, 4 + 83.98 (- 6 i) + (- 62.98 i) \cdot 0, 4 + (- 62.98 i) (- 6 i)

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

= 0 \cdot 83.98, 4 - 6 \cdot 83.98 i - 0 \cdot 62.98 i, 4 + 6 \cdot 62.98 ii

(x^{2} - 1) ln (x + 1) + x

\frac{d}{d x} (e^{(20 + 0.5 i) \cdot x})

(1 - cos (x)) d x - (1 - cos (y)) d y

\frac{1}{cos ( x ) ( sec ( x ) - tan ( x ) )}

\frac{4}{( x ^{2} + x ) ( x + 3 ) ( x ^{2} + 4 ) ( x + 2 ) ( x + 4 )}
